Definitions
- the invention relates to a hole saw, consisting of a basic body of cylindrical contour and end face on the main body annularly arranged hard particles.
- Such hole saws are used, e.g. To drill in ceramic tiles or similar holes of only a few millimeters, for example, to attach a dowel hole in the underlying wall can.
- the hole saw has at one end a hard particle coating capable of annularly severing the hard ceramic material to form a hole in the tile.
- Such hole saws typically have a diameter of only a few millimeters.
- these hole saws prevent a tile connected to the wall from bursting with the use of percussion drills or hammer drills, for example when installing a holder or the like in a bathroom.
- the object of the invention is to further develop the known hole saws so that the purpose of use is increased.
- the advantage of the invention is that either the service life of a single tool is easily doubled, and / or that holes of different diameters can be produced with one and the same tool.
- the tool according to the invention can have the same diameter at both ends or in each case different diameters.
- the cylindrical contour can e.g. have the cross section of a regular hexagon in order to hold the drill saw according to the invention against rotation in a conventional three-jaw chuck.
- the hole saw according to the invention may also have an annular cross-section, ie consist of a tube section of constant or varying diameter, wherein in each case a clamping surface must be provided on the outer circumference, which corresponds to a chuck.
- the tube cross-section in each case runs straight-cylindrical, except for an optionally necessary transition region from the smaller to the larger cross-section.
- the hollow-core hole saw is therefore capable of receiving the sawn piece of ceramic as soon as the hole saw has passed through the tile.
- the hole saw according to the invention is additionally coated in color, e.g. by paint or powder coating, the wear condition can be easily seen from a distance, so that if necessary replenishment can be procured in time.
- the figures show a hole saw. 1
- Such hole saw consists of a base body 2 of cylindrical contour.
- the main body 2 may, but need not, be hollow inside. It is also conceivable to hollow out the base body only at the ends and to make it in the middle axial region as a solid body in order to be able to apply, for example, high clamping forces.
- the main body 2 has on one end face 4 a coating of hard particles 3.
- holes of different diameters can be produced with a single tool.
- the clamping of the hole saw is expediently always carried out on that cylinder cross-section which is opposite to the current cylinder cross-section required for hole production.
- Clamping jaws of the drill chuck 8 can come there accordingly to the plant, as in particular the detailed representation
- Fig.3 illustrates.
- the main body 2 including its two front ends 5, 6 and the hard particles 3 located there, e.g. by painting or powder coating or the like.
